Guide surface 51 engages.Neck-shaped protrusion 53 and 45 telescopic slide of guide part cooperate so that connector 41 is in stroke adjustment
Direction S is accurately guided.
The tubular pars pectinata for especially surrounding guide part 45 with one heart equipped with connector 41 on the outer surface of connector 41
55, the pointer 61 of its outer surface cylindrical in shape for defining blind recesses 49 and radial projection extends from pars pectinata.Pointer 61 always from
It is all visually directions show connecting rods 11 and and then the operating parts (not shown) of regulating device position, whereby than adjust driving dress
The position that other forms in housing 3 more reliably illustrate the regulating device is put, other forms only show that stroke adjustment is driven
The position of the inner part of dynamic device 1.
Pointer 61 not only has the task of the position of instruction connecting rod 11, is also concentrated on as liquid outlet duct, the liquid
In connector 41 and adjusting driving device housing 3 region.
In order to see pointer 61 on the outside, sealing 63 is opened in circular mounting flange 65, and mounting flange has radially
The end clip protruded outwardly.Locking nut 71 and the end clip cooperation, the regulating valve not being shown specifically installation is expert at
Journey is adjusted in driving device 1.
The pars pectinata 55 and neck-shaped protrusion 53 of connector 41 form sealing surface on opposed inner surface or outer surface
54th, 56 clearance seal or the labyrinth seal for forming non-contact operation according to the present utility model.The axial seal face ruler
The very little position on axial S according to connector 41 is either large or small, it is apparent that these sealing surfaces always stroke adjustment movement in
Range of movement along connector 41 is axial overlap.In this way, neck-shaped protrusion 53 and pars pectinata 55 realize that labyrinth is close
Envelope, while function is visually indicated by the reinforcement of pointer 61.Connector 41 forms sealing surface 54, and adjusts driving device housing 3
Neck-shaped protrusion 53 forms the matching trim of the labyrinth seal in its outer surface.
As shown in figure 3, the sealing surface 54,56 extended in the axial direction is diametrically completely opposed and overlapping in the axial direction.
In this way, the fluid via through holes 13 perhaps outside of technique productions equipment enter inside stroke adjustment driving device 1
Flow path is obviously prolonged, and thus, the feature of connector 41 is also expanded further to seal in addition to indicating function
Function and drip function.
Feature disclosed in specification, drawings and the claims before it is not only possible individually and with any
Combining form is meaningful for realizing the utility model with different embodiments.
